THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 446,323, dated February 10, 1891.

Application filed June 23, 1890- Serial No. 356,439. (No model.)

[0 My invention pertains to certain new and useful improvements in thill-couplings, and

has for its object the simplicity and novel construction of the parts, as will hereinafter more fully appear from the following description and accompanying drawings.

Figure 1 is a side elevation of my invention. Fig. 2 isa sectionalelevationof the same, and Fig. 3 is a cross-section thereof on line a: 00.

In the embodiment of my invention I employ the ordinarily-constructed axle-clip A, secured on axle a and having the horizontal arms extending therefrom, secured between the outer ends of which is a rectangular crosspiece or support a.

Bar B is secured atits forward end to thill B by meansof bolts and has its rear end bifurcated, the two arms I) and l) of which are parallel neartheir extreme end and are formed into a circular recess at 0, intowhich recess a 3o cylinder (Z is inserted havinga recess (1 therein. The recess d is the same width as the space between the arms I) b, and is designed to receive the cross bar or piece a. It will be seen that when bar a is inserted in recess (1' and the thill is raised or lowered the draw-- bar revolves on the cylinder. The arms I) b are secured together by means of a bolt 5 projecting through said arms, which, being tightened, compensate wear of the thill and prevent rattling thereof.

Cylinder d has its ends beveled at (Z fitting flush against which beveled portion is a flange of the arms b b, bent over after the insertion of the cylinder in its bearing to prevent the lateral displacement of said cylinder. 5

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The thill-coupling consisting of the bar having one of its ends bifurcated to serve as a bearing for a recessed cylinder supporting a rectangular cross-bar in said recess, said arms being secured together at their ends by means of a bolt for tightening said arms to compensate wear of the thill, substantially as shown and described.

2. A thill-coupling consisting of the bifurcated draw-bar having inclosed therein the beveled cylinder, said draw-bar having the flanges bent over said cylinder, substantially as shown and described.

3. The thill-coupling consisting of the bi-- f urcated draw-bar having inclosed therein the beveled end cylinder,over which ends flanges of the draw-bar are bent, said cylinder being slotted or recessed for reception of a rectangular cross-bar, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
